Los Angeles regional pest management guidelines conform to research published by UC IPM Extension and the California Structural Pest Control Board (SPCB).
Southern California Climate & Pest Drivers
Greater Los Angeles features a Mediterranean climate with dry summers and mild winters. Western drywood termites (Incisitermes minor) infest exposed wood fascia and attic framing, while mega-colonies of invasive Argentine ants (Linepithema humile) stream indoors during summer heat waves seeking water. Roof rats nest in palm trees and ivy before entering attics via roof overhangs.
